机械行业变转速零件

MATLAB常用操作、符号、函数等等简要说明(MATLAB brief common operations, symbols, functions, etc. Description)

包括指纹图像的离散化，特征提取，gabor滤波等等。。(consist of dirImg,extract,gaborfilter,and so on.)

利用函数MadHG生成规则LDPC码的校验矩阵H，其行重为6,列重为3,行数为列数一半(行数越大越好)，H中任意两列没有围长为4的圈，并得到H对应的生成矩阵G，可以保证mod(G*H ,2)=0。使用方法为:[H,G] = MadHG(m,n,x),x= 1(得到的G左半部分为单位阵) or 2(G右半部分为单位阵),(use function MadHG Generation rules LDPC check matrix H, re-6, series of three, out for a few half of the number (A bigger the better), H 2 arbitrary no girth of the four circles, H counterparts and with the formation of matrix G, we can be assured of mod (G* H, 2) = 0. To be used : [H, G] = MadHG (m, n, x), x = 1 (the G part of the Left Front units) or 2 (G right half of the units RUF),)

This code can be used to detect copy move image forgery based on SIFT algorithm

经典的波束赋型代码，有均匀圆形阵列，均匀线性阵列，圆柱阵列，球形阵列等(Classic beamforming code, uniform circular array, uniform linear array, cylindrical array, ball grid array, etc.)

说明：  FM和PM的调制解调仿真源代码，已经调试通过。(FM and PM modulation and demodulation simulation source code has been debugged.)

带有电压恢复补偿功能的直流微电网下垂控制，适用于孤岛运行(droop control based on voltage compensation)

利用人脸肤色模型对一副图片的多个人脸进行人脸识别(Use of a skin color model images and more personal face to face recognition)

本程序比较了LS(最小二乘）和最小均方误差准侧下OFDM信道估计的误码率，给出了LS及MESE实现的源程序，是信道估计初学者的理想参考资料(This procedure compares the LS (least squares) and minimum mean square error of quasi-lateral channel estimation of OFDM bit error rate, given the realization of the LS and the MESE source, channel estimation is the ideal reference for beginners)

介绍了matlab程序设计方法，并给出了一些具体实例(it introduces matlab program designing method,and it gives some specific examples.)
